Reload OpenMeta Tags

Description

When importing a file, EagleFiler reads the tags from OpenMeta and sets the
EagleFiler tags accordingly. Additionally, tag changes made in EagleFiler
are written to OpenMeta (not necessarily immediately, unless you choose Backup
Metadata). This script lets you propagate changes in the other
direction, replacing the selected records’ tags with the OpenMeta tags that
are stored in the files’ extended attributes.

(Warning: There are various ways that OpenMeta tags can be inadvertently
deleted. If this has happened, running this script will remove the tags in
EagleFiler.)
